You can't compare anything to the 2100 yet, because it is not out, and most probably not yet in it's finished form. If Yamaha follows their usual form, we won't see it for many more months.
Also, please consider whether the operating system will be in Flash ROM. As we know, it was promised and advertised on the 2000, but that was not true. ("Not true" sounds better than "a lie".)
